Protesters on a flotilla which left Australia last month are expected to cross the marine border of the Indonesian Province of Papua on thursday.

The demonstrators have been warned by Australia's Department of Foreign Affairs and Trade they won't receive any consular help if they're arrested.

Protest organiser Izzy Brown gave Pacific Beat an update from the flotilla's flagship on thursday morning.

"We've just crossed the PNG border and we've picked up speed to about six knots. Well there's six people on the boat, we're about 15 nautical miles from the Indonesian border." Ms Brown said.

"We're hoping we'll be able to enter into some negotiations with them via direct tech radio and at least talk to them and see what their response is."

The so-called Freedom Flotilla is heading for West Papua in protest at the charges of treason against four community leaders.

The Indonesian government have also said they could face five years in prison for violating their immigration laws.

Ms Brown said they are prepared for what they might face.

"Surprisingly morale is quite good on board. I think there's an undercurrent of nervousness but so far the mission has been success and we've managed to draw a lot of attention to the situation in West Papua." Ms Brown said.

"If they do turn us back then that's something we'll have to deal with and hopefully we can negotiate something without being arrested and serving time."
